			// 2. Logged into Facebook, but not your app ('not_authorized')
			// 3. Not logged into Facebook and can't tell if they are logged into
			//    your app or not.

  Below we include the Login Button social plugin. This button uses
  the JavaScript SDK to present a graphical Login button that triggers
  the FB.login() function when clicked.
